Effects of prenatal care on twin gestations.

Twin pregnancies are known to have a higher risk of prematurity, uteroplacental insufficiency and increased perinatal mortality. An almost universally held tenet is that prenatal care is helpful in reducing those risks. In an attempt to support that belief, the records of all twins delivered at R.

Direct chromosome analysis from neonatal cord blood.

Direct chromosome preparations of neonatal cord blood provides the unique opportunity for rapid chromosome analysis (turnaround time; 6 hr), without the necessity of bone marrow aspiration. Based on 42 samples we confirm the finding of Garnham and Sutherland [1987] for suitability of cord blood for direct chromosome preparation. Procedural modifications are provided for higher yield of cells for chromosome analysis.

Perinatal complications in group B streptococcal carriers: a longitudinal study of prenatal patients.

Although prenatal group B streptococcal detection and eradication have been proposed to prevent morbidity, the risk of perinatal complications in prenatal carriers of group B streptococci has not been defined. We evaluated 718 prenatal patients with serial cultures to compare morbidity in carriers and noncarriers. Complications occurring more frequently (p less than or equal to 0.
